Investigate the core team behind the project. Find out if the team members actually exist.
Do they have a track record or experience that is relevant to the project that is verifiable?
Searching social media sites is a good place to start but perhaps more important is establishing if the individual in question is involved with any other projects or discussions related to the projects development. If the person presented to the public seems too generic, their profiles have little social activity or if their association with the project is unclear then this should arouse suspicion.
